As previously discussed, Ngg is found for each mode and polarization by solving either (1) in the case of a single-layer waveguide or (40) for the more complex configurations. 

As a result of the work summarized in this chapter, unprecedented spectro-electrochemical sensitivity is now available in the visible wavelength region using broadband, single-mode waveguide platforms overcoated with semi-transparent conductive oxide electrode layers [3-5]. For certain molecular systems, it is now possible to monitor ET events for surface coverages of just a few percent of a monolayer moles/cm ). This work has spawned the development of broad-... 

This poled polymer was 3RDCVXY which exhibits a value of 80 pmA and a optical loss of 0.65 dB/cm in the form of a single-mode waveguide operating at 1.3 pm. AUV cured epoxy resin is also used as a core. The refractive index of the UV cured resin can be easily controlled(25). This controllability makes it easy to form a periodic laminar structure composed of poled polymer and UV cured resin with almost the same refractive index. On top of the silicon substrate, a low refractive index UV cured epoxy resin is spin coated as an under-cladding layer of the waveguide. Core...

A novel polymer optical waveguide switch has been fabricated which uses total internal reflection from a thermally induced index barrier created by a silver stripe heater. In this case, polyurethane with An of -3.3 X 10 C" was used for the switching layer and PMMA was used for the substrate and buffer layers. A small part of the polyurethane film was left uncovered by the PMMA buffer to allow for injection of 632.8 nm He-Ne laser light into a single-mode waveguide by means of a prism-...
